81Disjunction and existence properties — In mathematical logic, the disjunction property is satisfied by a logic if whenever a sentence is a theorem, then either ϕ is a theorem, or ψ is a theorem. The existence property or witness property is satisfied by a logic if whenever a sentence… …
82Cartan matrix — In mathematics, the term Cartan matrix has two meanings. Both of these are named after the French mathematician Élie Cartan. In an example of Stigler s law of eponymy, Cartan matrices in the context of Lie algebras were first investigated by… …
83List of mathematics articles (A) — NOTOC A A Beautiful Mind A Beautiful Mind (book) A Beautiful Mind (film) A Brief History of Time (film) A Course of Pure Mathematics A curious identity involving binomial coefficients A derivation of the discrete Fourier transform A equivalence A …
84Solenoid (mathematics) — This page discusses a class of topological groups. For the wrapped loop of wire, see Solenoid. The Smale Williams solenoid. In mathematics, a solenoid is a compact connected topological space (i.e. a continuum) that may be obtained as the inverse …
85Horrocks-Mumford bundle — In algebraic geometry, a branch of mathematics, the Horrocks–Mumford bundleis an indecomposable rank 2 vector bundle on 4 dimensional projective space P 4 named after Geoffrey Horrocks and David Mumford.It is the only such bundle known, although… …
86Still life (cellular automaton) — In cellular automata, a still life is a pattern that does not change from one generation to the next. A still life can be thought of as an oscillator of period 1. A strict still life is an indecomposable still life pattern, while a pseudo still… …
87Composant — In point set topology, the composant of a point p in a continuum A is the union of all proper subcontinua of A that contain p. If a continuum is indecomposable, then its composants are pairwise disjoint. The composants of a continuum are dense in …
88Generalized Helmholtz theorem — The generalized Helmholtz theorem is the multi dimensional generalization of the Helmholtz theorem which is valid only in one dimension. The generalized Helmholtz theorem reads as follows.Let:mathbf{p}=(p 1,p 2,...,p s), :mathbf{q}=(q 1,q 2,...,q …
89Weyl character formula — In mathematics, the Weyl character formula in representation theory describes the characters of irreducible representations of compact Lie groups in terms of their highest weights. It is named after Hermann Weyl, who proved it in the late… …
90Robbins pentagon — A Robbins pentagon, named after David P. Robbins, is a cyclic polygon with five integer sides and integer area. It also has the property that all its diagonals are rational which means that it can be decomposed into Heron triangles. The converse… …
